为加快我系统钻探设备更新改造的步伐和金刚石钻探技术的推广速度,1982年冶金部地质局对YL-3型钻机组织了鉴定,并安排由中南冶金地质机修厂成批生产,鉴于这种钻机是当前用量较大,适用范围较广,性能较先进的新设备,为使更多的钻探人员了解其性能特点,掌握其操作使用方法,本刊从本期起开辟“YL-3型钻机讲座”专栏,陆续介绍钻机的性能特点,主要部件及附件结构,液压系统,安装与操作使用,维护保养与故障排除等内容,希读者注意.
In order to speed up the renewal of drilling rigs and the promotion speed of diamond drilling technology, the YL-3 drilling rig was organized and appraised by the Metallurgical Bureau of Geological Administration in 1982 and arranged to be mass-produced by Zhongnan Metallurgical and Geological Bureau. In view of this rig Is the current larger amount, wider scope of application, more advanced performance of the new equipment, in order to enable more drilling personnel to understand its performance characteristics, to master the operation and use of methods, this issue from this issue to open up "YL-3-type drill rig Column, one after another on the performance characteristics of the rig, the main components and accessories structure, hydraulic system, installation and operation, maintenance and troubleshooting content, hope readers attention.
